Fisher CZ Forum

I am 61 years old and metal detecting has been my hobby since 1982.During this time I have used one tone detectors However,recentlyI purchased a Fisher cz-3d and a 5 inch coil.Ihave researched all the good posts on the CZ classroom forum along with having information e-mailed to me. After reading multiple posts about users digging up square nails, I have one question. Would it be possible to avoid this by using the iron discrimination, or will they still be in the high tone coins mode? Any information on this will be appreciated. Thanks very much, Bill-NC.

All units have give and takeaways and a CZ is certainly one of the deepest units around but does like those pesky deep rusty nails and discriminating iron will not help...Go to Mikes CZ page as it has many tips to avoid the problem..Any new CZ owner will unfortunately have this problem, but time in the field and reading the tips you will dig very little..I dig very few after using a CZ for years and after a while you will also learn how to avoid them. We are all fooled from time to time especially going for an extremely deep iffy but after a while all will fall into place and you will dig very few of them....Mikes CZ page http://mikewd.fws1.com/

Bill, I think you will find your cz to be not that much different from most detectors when it comes to (deep) rusty nails or small nail fragments. I also think your going to like the 5" coil on that machine. Good luck to you.

Bill, how I deal with deep iron , or how to minimize digging it, when you pinpoint the target you will be able to trace its size .... a small tight pinpoint is what you want , the iron targets usually are elongated. Give it a try , it works for me . I rarely dig any iron . HH Tony
